    Ordered another Yuasa battery for the owner recently.


    In 2019, I ordered the same model for myself.
    On this occasion, several changes with the design,

  2. Speaker - Repair

    Introduction
    Failure of the NSX active speakers is a common fault, especially for the early build years. The modules are class-D switching amplifiers with a MOS-FET driver bridge for low impedance (2 Ω) speakers. The amplifier can be divided into these main sections:

    • Output drivers (MOS-FET transistors) and Filter (coils)
      One pair of transistors connects one pin of the speaker to either GND or VBAT. The IC U2 ensures that two opposing transistors are never conducting

  5. Airbag (SRS) - Capacitor Replacement

    Introduction
    The Supplementary Restrain System (SRS) ECU suffers from ageing capacitors the same way as many other ECUs in the NSX. Two things makes it a special issue: The SRS is a safety device and a permanently lit warning light means failing the regular vehicle checks in most countries.
    Especially the first generation ECUs (cars with only a driver's Airbag) tend to fail by shorting an important MOS-FET inside the housing which complicates repairs.
